(3) In snowy regions, be sure to install a snow-protection hood and enclosure.
Even in regions that do not have heavy snowfall, install a snow-protection roof (such as a snow hood) if the
unit is installed in a location where snow may build up and fall from the building's roof or other surface onto
the unit. (Install the hood so that the coolant supply opening at the top of the unit can be used.)
(4) Take care that operating noise and exhaust do not disturb neighboring buildings or homes.
In particular, install so that noise-related local environmental standards, if any, are satisfi ed at the border
with a neighboring dwelling.
(5) Electrical noise resulting from this gas heat pump A/C may affect other electrical devices. When installing
and wiring, take care to leave suffi cient space (3 m or more) between the A/C units (indoor and outdoor
units) - or the power cables - and any other units, antennas, signal cables, or power cords of televisions,
radios, stereos, intercoms, computers, word processors, telephones, and similar devices.
(6) Select an installation location so that the length of refrigerant tubing is within the ranges shown in the table
below.

Maximum length from the fi rst T-tee to the last T-tee
(*1) The minimum length of tubes between outdoor units and indoor units is 7 m.
(*2) If cooling mode is expected to be used when the external temperature is 10°C or below, install so the
maximum length is 30 m.
(*3) Install so that the height difference between indoor units after the fi nal branch is within the limits shown in
the fi gure on the next page.
The grouping of tubes that connect the outdoor units to the indoor units is referred to as the "main tubing."
When the maximum tubing length is more than 90 m (equivalent length), upgrade the tube size 1 rank for
both the liquid and gas tubes of the main tubing.
The prescribed performance cannot be guaranteed if the wrong size is selected.
